Exploration of Medical Volume Data in Projective Augmented
Reality: An Interactive Demonstration
Kai Bornemann, Florian Heinrich, Kai Lawonn, Christian Hansen
This article describes the implementation and usage of a prototype
to explore medical volume data in projective augmented reality
(AR). To allow real-time rendering of the data, a volume ray casting
algorithm is implemented on the GPU. Furthermore, the volume
data is distorted to be superimposed correctly from the user’s perspective.
To allow exploration of the dataset, the user can use an
HTC Vive Controller to show or hide structures with either clipping
or windowing. In the future, the proposed prototype might be
used for diagnosis, planning and computer assisted surgery. First
tests indicate that this setup increases spatial understanding of the
volume data compared to conventional computer monitors.
